BackAndroid is still exported to ReactNative for now, until external projects switch to using the new name for the module.

Summary:
The PR description has been updated to reflect the new approach.
**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
On Android with dev mode on, we're seeing a regular SIGSEGV when pushing a lot of animation declarations over the bridge. We tracked this down to being not specific to animations, but the crash is caused in `deepFreezeAndThrowOnMutationInDev`.
Specifically: the provided object to freeze is modified while looping, replacing the current key access to a getter/setter. After the modification, JSC crashes during retrieval of the next key - but only when there are a lot of events passing over the bridge.
We have a hunch that this is due to a bug in JSC object enumeration but did we not look into it further yet. Any help here is welcome. The JS code seems all right at first sight and shouldn't cause a segmentation crash.
The workaround in this PR is to retrieve the keys first from the object and then looping over that array. In our app and in a reduced app test case this fixes the crash.
If needed I can provide the reduced app test case. It's really tricky to make a test for this as it requires to be run

Summary:
**Motivation**
In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS.
This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value.
This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean))
**Usage example**
```js
Alert.alert(
'Alert Title',
null,
[
{text: 'OK', onPress: () => console.log('OK Pressed!')},

Summary:
This diff
- creates `XHRInterceptor` to intercept all XMLHttpRequest network operations in React Native by monkey-patching.
- enables `XHRInterceptor` in RN development tool "inspector".
This interception and inspector tool work well on both Android and iOS. And this supports interception on any network API based on XMLHttpRequest, especially the Fetch API.
By now, we can intercept 12 information fields of a XMLHttpRequest including method, url, data sent, status, response type, response size, requestHeaders, responseHeaders, response, responseURL, responseType and timeout.
Follow-up:
- Will add UIs in the inspector on top of this diff, to display all the network operation information. (Not in this diff just to make this shorter)
- Will extend this to gather other valuable information towards one XMLHttpRequest.
- Should support other network request APIs like WebSocket.

As part of improving the API and Component reference docs #8154 this pull request adds the following:
- jsdoc support for API docs. See the AlertIOS changes as an example.
- type definitions support and added to both API and Component docs. This is supported via react-docgen and jsdoc.

FYI, API and Component docs were previously generated in two different ways. Components were using react-docgen and that basically remains as-is. APIs were using custom parsing code and that's been switched to use a jsdoc parser + react-docgen as an option for typedefs (it could also use the jsdoc parser).
Two docs have been updated to showcase how we'd like the new docs to look:
- AlertIOS (API): showing method parameters, examples, typedefs, more details overall.
- Statusbar (Component): showing method parameters, typedefs, more details overall.

Summary:
transformMatrix only worked on iOS and there is an equivalent API that (mostly)
works cross platform.
decomposedMatrix could technically be passed on Android but it wasn't document and explicitly flagged as not working.
My goal is to deprecate both uses and then the only supported API is the `transform: [{ matrix: ... }]` form.
The only difference is that on Android the matrix gets decomposed.
Currently there is some special cased magic that renames transform -> transformMatrix or decomposedMatrix depending on platform.
https://github.com/facebook/react/blob/master/src/renderers/native/ReactNative/ReactNativeAttributePayload.js#L50
Therefore I'm adding an alias for both native platforms called just "transform".
Next I'll swap over the JS to always target the name "transform". The only difference is how the value is marshalled over the bridge in processTransform.
To do this, I have to clean up a few callers. Mostly that's just swapping to the new API.
For buildInterpolator this is a bit trickier but this fixes it for all our use cases (which is only the Navigator in AdsManager).

Summary:
This only works for the new cxx bridge (hopefully open sourcing soon!).
This diff allows Java native modules to expose synchronous hooks to JS via the ReactSyncHook annotation. The methods will appear in JS on the native module object (e.g. you would do `require('UIManager').mySyncHook('foo');`) which allows us to enforce that required native modules are installed at build time. In order to support remote debugging, both the args and return type must be JSON serializable (so that we can go back across to the device to resolve synchronous hooks).
Follow ups will be integration tests, adding support for return types besides void, and adding support for remote debugging.

Kudos to frantic for this amazing idea! Works really well (yet so simple!)
Basically we had a discussion with vjeux and frantic and others in the PR #7033 how to handle platform-specific stylesheets in a similar to F8 app way.
There were quite a few nice ideas there, however that one seems to be the smallest yet the most powerful.
Basically there's a `Platform.select` method that given an object, will select a `obj[Platform.OS]` value.
It works with styles:
`Platform.select({ ios: {}, android: {} })`
with messages:
`<Text>{Platform.select({ ios: 'Check the App Store', android: 'Check Google Play' })}</Text>`
